SASS partials are files with names starting with _. They should not be processed by Brunch.

There is often a main SASS file which imports others, for instance both _mixins.scss and _foo.scss. If _foo.scss is processed, it will not have access to _mixins.scss and Brunch throws errors.

Adding something like return if /\/_/.test path in the SASS compile method should work.

You can read more about partials at http://sass-lang.com/docs/yardoc/file.SASS_REFERENCE.html#partials
